PROCESS OI PRINTING- AND MACHINE THEREFOR.

Application filed July 31,-1919. I Serial No. 314,481.

To all whom it may aoncernr Be it known that I, RALPH G's-JACKSON, a citizen of the United States, and a resident of Chester, county of Delaware, State of Pennsylvania, have invented certain Improvements in Processes of Printing and Ma:

chines Therefor, of which the following is a specification.

} My invention relates to certain improvements in flat block printing machines, in which a series of impressions are made to form a continuous design or pattern.

The object of my invention is to'increase the production of such a machine without increasing the size of the block.

It is found in practice that a block 18" wide is the maximum width in which a block can be made for producing high grade printing. It has been the universal practice to feed the material intermittently the width of the block at each movement. These blocks are so arranged that difierent blocks print different colors on the same ortion of the material so that one block wi 1 make an impression on the entire'surface of the material consequently, the movement of the material is limited by the width of the blocks.

By my invention, however, I print on one section of the machine alternate spaces by one set of blocks and on the other portion of the machine I print the intervening space by another set of blocks. The two sets of blocks, where the design is a repeat, are similar and the colors are similar, so that the material can be moved a distance equal to twic the width] of the block and, consequently, will travel through the machine at a greater speed than heretofore.

'- In the accompanying drawings:

ig. 2 is a side view ing one of the essential also in outline, showparts of the machine;

movement to the block carriers. T ese shafts 6 are driven from a longitudinal shaft 7 throu in suitable gearing. Latches 8 are for holding any of the block carriers out of action and mechanism such as illustrated in the above mentioned ll/'aldron patent, may be used for automatically operating these latches, if'desired.

9, 9' are the mechanism for inking the block carriers and are recip-rocated through means at one end of the machine so that when the blocks are raised the several inking mechanisms are'traversed under their res ective blocks and ink the printing sur' ace thereof.

At each side of the machine are tapes 10,

which pass aroundwheels 11 at each end ofgiven movement to the tapes 10. The gear I wheels 14 and 15 mesh with gear'wheels 17 and 18., respectively, on a shaft 19 having a star wheel 20, which is intermittently rotated by a pin wheel 21 one. shaft 22 geared to the shaft 23 which, in turn, is driven from the longitudinal drivin shaft 7 when the clutch 16 is in mesh Wlth the gear wheel 14. Then the tapes 10 travel the ordinary distance, i. e., 18", but when the clutch is in mesh with the gear wheel 15- the tapes 10 travel 36". B providing this clutch mechanism, the mac ine can be used for ordinary printing, i. e., in which the material travels 18", or it can be used for carrying out my im roved process in which the material trave s 36".

In the present instance, I have shown six printing blocks, three on one portion of the machine and three on the other portion of the machine. These blocks are 18" in width and are spaced 18" apart, but the space at between the two sets of blocks is 36 so that while the blocks a, a, a print the 1 sections of the material in'three colera, the blocks 5, b, b print in three colors on the spaces e of the material as clearly shown in Figs. 3, 4 and 5. v

If the design be a continuous design, as

illustrated in Fig. 5, then the design on 7 design on\ the blocks a, a, a

each of the blocks 1), b, b is similar to the It will be noticed that where rugs are ing printed, or a continuousmaterial is being printed in which the alternate spaces are of a different design, then the blocks 6,

a, and may also differ in color.

Thus it will be seen that while the blocks are of the standard width, the movement of the material is twice the width of the blocks,

consequently, the production is considerably increased without increasing the speed, the movement of the blocks, or the speed of the reciprocating movement of the inkin mechanism, as the speed of the inking mec nism is limited, owing to the character of the ink or pigment. v

While I have illustrated my invention as applied to a flat block printing machine, it

will be noticed that the invention can be carried out in other types of printing machines, in which blocks or sections aroused for printing a given surface of material.

' 1. The process herein described of printin material in a flat block printing machine, said process consisting 1n making a series of impressions of a given width and spaced apart, the spaces being equal to the width of the impressions, then making a se ries of impressions on the spaces left blank by the previous printing, the designs of the ,two sets of impressions being similar; and

intermittently feedin the material a distance equal to the width of two blocks so that the impresions will make a continuous design.

. mascara 2. The combination in a flat block printing machine, of two series of blocks equal in width, each series of blocks being spaced apart, thespaces being equal to the width of the blocks and the space between the two series of blocks being twice. the width of a block; and means for intermittently feeding the material through the machine, each intermittent movement being equal to twice the width of the blocks so that the first complete impressions are spaced apart and the final impressions are made in the spaces between the first mentioned impre$i0ns.

3. The combination in a block printing machine,'of anframe; a series of printing block carriers; means for operating the car-' riers; printing blocks'mounted on the carriers, the carriers being arranged in two sections, the'space between the sections being greater than the space between the'block's of each section; a power operated shaft; two gears-on said shaft; a shaft having wheels;

and material-carrying bands arranged to travel over the wheels two gears loose on the said shaft and differing in diameter; a

clutch arranged to throw either of the gear in en agement with the shaft so that when the c utch is in engagement with one gear, the material will move a distance equal to the width of the block and when the clutch is in enga ment with the other gear the material w ll be moved twice the distance of RALPH G.
